7 title: Microchip USB5744 4-port Hub Controller
10 Microchip's USB5744 SmartHubTM IC is a 4 port, SuperSpeed (SS)/Hi-Speed (HS),
11 low power, low pin count configurable and fully compliant with the USB 3.1
13 (LS) USB signaling, offering complete coverage of all defined USB operating
14 speeds. The new SuperSpeed hubs operate in parallel with the USB 2.0
16 USB 2.0 traffic.
